As more and more studies have come out showing that prior infection confers long-lasting immunity – not just the 90 days we are told by the government – the purveyors of panic and tyranny have sought to use the focus on several supposedly new variants to deny the presumed immunity from prior infection. However, a new comprehensive study from Harvard Medical School and Boston University researchers should put this latest myth to rest.
The researchers took blood samples from people who had the virus from March 3 to April 1, 2020, long before the new variants were discovered, which allowed them to presume they all had the original Wuhan strain. They found the S-specific memory B cells “conferring robustness against emerging SARS-CoV2 variants” – the U.K. (B117) & South African (B1351) variants.
“Loss of protection against overt or severe disease is not an inevitable consequence of a waning serum antibody titer,” wrote the authors. “This atlas of B cell memory therefore maps systematically a crucial component of the long-term immune response to SARS-CoV-2 infection.”
In other words, the inherent immune system full of B cells (in addition to T cells) provides robust immunity not just long after the antibody titers wane from the original infection, but also against emerging strains of the virus. — Source
